What MTProto is
MTProto is Telegram's own protocol for all client-server communication. An MTProto proxy wraps this protocol so the traffic looks like "random noise" to ISPs and DPI systems — hard to classify and block.
Why MTProto when SOCKS5 exists
- Block resistance — SOCKS5 is visible to DPI as a "socks connection", MTProto disguises as TLS
- Speed — MTProto is tuned for Telegram, less packet overhead
- Simplicity — only a secret is needed, no username/password
- All features work — calls, video messages, stickers run with no delay
How it works
The Telegram client connects to the MTProto server. The server receives an encrypted stream, decrypts the outer layer and forwards the inner MTProto traffic to Telegram's real servers. The encryption key (secret) is known only to the client and the proxy.
Data format
Instead of username/password MTProto uses a 32-char hex secret like dd123...abc. In the Telegram client you enter host, port and this secret — that's it.
Common questions
Can MTProto route non-Telegram traffic? No. The protocol is Telegram-only.
Good for multi-accounting? Yes. One MTProto proxy = one account.
Works in all clients? Yes — Desktop (Windows/macOS/Linux), iOS, Android, web.
